Order Tay-Sachs Disease Testing | Carrier TestTay-Sachs disease is a rare inherited disorder that progressively destroys nerve cells in the brain and spinal cord. This blood test measures the activity of hexosaminidase A (hex A), an enzyme that is deficient in individuals with Tay-Sachs disease. The test can determine whether a person has Tay-Sachs disease or is a carrier of the disease.
About Tay-Sachs Disease Testing | Carrier Test in Napa
Tay-Sachs disease is caused by mutations in the HEXA gene, which provides instructions for making the alpha subunit of the enzyme beta-hexosaminidase A.
This enzyme is found in lysosomes, which are structures that digest and recycle materials within cells. Hex A plays a critical role in the nervous system by breaking down a fatty substance called GM2 ganglioside. When Hex A is deficient, GM2 ganglioside accumulates to toxic levels in the brain and spinal cord, leading to the destruction of nerve cells.
Tay-Sachs disease has three forms: infantile, juvenile, and late-onset. The infantile form is the most common and severe, typically appearing in the first few months of life. The juvenile form is rare and usually appears in childhood, while the late-onset form can appear in adolescence or adulthood with milder symptoms.
Tay-Sachs disease is inherited in an autosomal recessive pattern, meaning that both copies of the HEXA gene in each cell must have mutations for the disorder to occur. Carriers have one mutated copy of the gene and typically do not show symptoms, but they can pass the mutation to their children.
